CENTRIFUGAL FLOUR-BOLT..

SPECIFICATION forming part of Letters Patent No. 308,844, dated December 2, 1884.

Application filed August 8, 1883. (No model.) I

To all whom it may concern.-

Be it known that 1', J OSEPH KUHNMiiNoH, of the city of Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Oentrifu gal Flour- Bolts, of which the following is a specification.

This invention relates to an improvement in that class of flour-bolts which are provided with revolving beaters or spreaders arranged within the revolving reel; and it has for its object to provideasimple mechanism whereby the revolving heaters or spreaders can be adjusted toward or from the inner surface of the revolving reel, in order to regulate the intensity of the bolting action.

My invention has the further object to improve the action of the boaters or spreaders in distributing the material over the boltingsurface; and my invention has also the object to provide a simple mechanism whereby the revolving reel is rotated directly from the beater-shaft.

My invention consists of the improvements in the construction of the flour-bolt which will be hereinafter fully set forth, and pointed out in'the claims. I

In the accompanying drawings, consisting of two sheets, Figure 1 is a longitudinal'section of aflour-bolt provided with my improve ments. Fig. 2 is an end elevation of the bolting-cylinder, showing the driving mechanism. Fig. 3 is a crosssection in line a" m, Fig. 1. Fig. 4 is a sectional elevation, on an enlarged scale, of one end of the machine. Fig. 5 is a cross-section of one of the heaters on an enlarged scale. Fig. 6 is a perspective view of a portion of one of the beaters. Fig. 7 is a cross-section in line on a, Fig. 4.. Fig. 8 is an enlarged elevation of the mechanism whereby the bolting-cylinder is rotated from the beatershaft. 1

Like letters of reference refer to like parts in the several figures.

A represents the inclosing-casing, B the revolvin g b'olting-reel arranged within the same, and G the beater-shaft arranged axially in the v bolting-reel and extending through the, same.

D represents two or more systems of spiders or arms secured to the shaft 0, and Ethe beaters or spreaders arranged in the bifurcated ends d of the arms D, so as to be capable of movement toward or from the inner surface of the bolting-reel B.

F are levers pivoted in the arms D near the shaft 0, and f are rods which connect the front ends of the levers F with the heaters E. The rear portions of the levers F are bent or curved inwardly, so that their rear ends approach the beater-shaft O.

G G are conical or tapering collars which surround the shaft G and project with their small ends between the rear ends of the levers F. The latter are held against the cones by the centrifugal force, which tends to drive the heaters E outwardly between the bifurcated ends or jaws d of the arms F.

g is a longitudinal slot formed in the shaft Oat the point where the cone G surrounds the same, and gis a rod or pin which extends di ametrically through the bore of the coneGand through the slot 9.

It represents a longitudinal shifting rod, which extends outwardly from the bolt 9 through an axial bore formed in the shaft 0, and which is provided at its outer end, which projects beyond the shaft, with a knob or button, H. The latter is free to turn on the rod h, and can be conveniently seized for pushing the rod h inwardly or drawing it outwardly for adjusting the heaters.

'i represents an enlarged portion of the rod it, provided with circular collars or ringshaped projections i, and I represents one or more spring-catches, which are secured to the shaft 0 in recesses '5 formed in said shaft, and which engage with their tapering heads in the grooves between the rings or collars 2", so that they hold the rod it against longitudinal movement under the ordinary pressure which is applied to the rod by the centrifugal force acting on the boaters. Upon pulling or pushing the rod h in either direction the inclined heads of the catches I are forced out of the grooves and ride over the rings or collars of the portion 73 until the movement of the rod h ceases, when they engage in the grooves and hold the rod in this position. The collar Gris connected with the collar G by a rod, K, so that both collars are moved simultaneously by adjusting the rod 71.. Upon drawing the rod h forwardly, so that it forces the collars G G between the rear ends of the levers F, the

latter are swung on their pivots, and this movement of the levers is transmitted to the heaters E by the rods f in such manner that the heaters are moved inwardly or away from the inner surface of the bolting-cylinder 13. Upon pushing the rod h backwardly the collars G- G are withdrawn from the inner ends of the levers F, and the heaters E permitted to move toward the inner surface of the boltingcylinder under the outward pressure of the centrifugal force. In this manner both ends of all the heaters can be adjusted simultaneously toward and from the bolting surfaee, thereby regulating the intensity of the bolting action. The inner faces of the rear portions of the levers F are curved or inclined to fit snugly against the tapering collars G G. The heaters E are arranged parallel with the beater-shaft 0, and provided along their edges with inclined scoops Z, which project forwardly from the edges of the heaters in the direction in which the heaters revolve, and are inclined in such manner that they will propel the material toward the tail end of the machine. The scoops l are preferably made of tin bent to the proper inclination, as represented in Fig. 6,.so as to leave an open space, Z, between the rear end of one scoop and the front end of the next adjacent scoop, through which the material is discharged against the bolting surface. These scoops pick up the material which may accumulate on the lower portions of the bolting-surface, and distribute the same successively by centrifugal force over the entire circumference of the reel without forcing it instantaneously againstthe surface of the reel, like ordinary heaters, or like flights which project rearwardly from the heaters, thereby avoiding an excessive pressure of the material against the bolting-cloth, which tends to wear out and burst the boltingsilk.

M M represent the annular heads or rings, which are arranged at the ends of the boltingcylinder, and to which the bolting-cloth is secured. These rings are provided on their outer sides with rings m, of leather or other suitable material, which are provided with eyelets or hooks m. The strips of ticking, a, which are secured to the ends of the bolting-silk, are provided with similar eyelets or hooks, a, which are connected with thehooks or eyelets m by laeings or cords 0, by which the cloth is secured to the heads M and properly stretched. The strips a of ticking are drawn over the outer edges of the rings M, so that the lacing is arranged on the outer side of each head M, where it can be easily reached when it is required to be adjusted. Each end of the casing A is provided with a removable end piece, N, by which access can be had to the lacing. The longitudinal edges of the cloth are also secured together by a similar lacing.

P represents grooved friction -w.heels secured to the beater-shaft 0 within the rings M, and q represents a friction-rim formed on the inner side of each ring M.

R R represent supporting friction-wheels arranged within each rim q, so as to run in contact with the friction-rims q and support the rings M above the heater-shaft. The frictionwheels R turn on studs T, which are attached to brackets 1-. The two brackets r of the pair of friction-wheels R at each end of the machine are adj ustahly secured to a standard, S, which is supported upon a bridge-tree, S, in which is formed a bearing, 8, in which the shaft 0 turns. T represents a transmitting friction-wheel arranged above the friction-wheel P at each end of the machine, and running in contact with the friction-wheel P and with both supporting friction-wheels R R at the same end of the machine, so as to transmit the motion from the wheel P to the wheels R B. Each wheel T is provided witha stud or arbor, t, which turns in a bearing, 16. The latter is made vertically adjustable in the standard S by a screw-bolt, t passing through an elongated opening in the standard, so that the position of the wheel T can be adjusted with ref erence to the wheel P to insure the necessary frictional. contact. The upper portion, S of the standard S is made vertically adjustable on the lower portion of the standard by a slot, 5, and bolt 8 or otherwise, and the brackets r are secured to the upper adjustable part, S of the standard, so that the wheels It R can be adjusted vertically to conform to the adjustment of the intermediate wheel, T. The brackets r are secured to the upper portion, 8 ,01 the standard by bolts 1 and curved slots 1*, made concentric with the wheel T, so that each of the wheels R can be separately adjusted to regulate the position of the bolting cylinder with reference to the heaters.

In some cases brushes may be substituted for the heaters; or brushes and heaters maybe employed in the same machine, as the material or the nature of the work may require. These heaters or brushes are readily adjusted toward or from the bolting-surface while the machine is in motion, the knob at the end of the adjusting-rod being grasped by the operator for shifting the adjustable beater-supports while the adj usting-rod revolves freely.

I claim as my invention- 1. The combination, with a bolting-reel, of revolving heaters or spreaders arranged in said reel, a rotating shaft extending through the reel, adj ustahle supports whereby the heaters or spreaders are connected near both ends with said shaft, mechanism whereby both series of adjustable supports are moved simul taneously to adjust the heaters or spreader-s toward or from the bolting-surface, and an adj usting-rod extending outwardly through an opening in said shaft, substantially as set forth.

2. The combination, with a reel, of a rotat ing shaft extending through the reel, arms secured to said shaft, heaters guided in said arms, adjustable levers attached to said arms, rods whereby the levers are connected with the heaters, and cones whereby the adjustable levers are moved simultaneously to adjust the heaters toward or from the bolting-surface, substantially as set forth.
